YFull

The same branch on YFull #

YFull builds its tree from the same SNPs; the node is matched by name or by a shared SNP. TMRCA is when the common ancestor of all samples lived, formed is when the branch split from its parent. Intervals are 95%.

J2b: 603 samples. The common foremother lived 13k years ago (8,200–19k); the branch split off 20k years ago (20k–20k).
